1 Electricity Market Reform and the UK's liberalised energy market The Institute of Energy Economics Japan Tokyo 3 March 2015 Jim Skea Research Councils UK Energy Strategy Fellow

2 Structure of talk Drivers of Electricity Market Reform (EMR) What problem is EMR intended to resolve? Historical context Elements of EMR Future policy options

3 The drivers of electricity market reform (EMR) 1) Climate change policy (Climate Change Act 2008) 2) EU Renewable Energy Directive 2009 implies ~30% renewable electricity by 2020 (15% energy including heat and transport)

4 Changing energy policy priorities climate affordability security

5 UK carbon budgets Source: UK Committee on Climate Change

6 Progress in meeting carbon budgets

7 Decarbonisation will require GW new low-carbon capacity through the 2020s 36 GW new capacity in 2020s Note: Intermittent technologies are adjusted to be baseload equivalent

9 Low carbon electricity is capital intensive.. Source: Mott McDonald

10 But intermittent generation = volatile prices in an energy only market Source: Committee on Climate Change

11 EMR: What s the problem? Low carbon electricity generation tends to be high capital cost/low running cost (fossil plant with CCS excepted) Investment in such plant is exposed to additional market risk in a volatile energy only market Gas plant has a natural hedge because gas prices drive electricity prices and hence has lower risk The cost of capital is therefore higher for low carbon generation The purpose of Electricity Market Reform is to reduce market risk for low carbon generation by offering stable prices This also helps to contain the cost to consumers of low carbon electricity supply

13 Historical context Wholesale electricity Retail electricity 1990 Privatisation - Unbundling, generation duopoly, power pool arrangements, but bilateral contracts for differences (CfDs) emerge 2001 New Electricity Trading Arrangements (NETA) bilateral contracts plus spot market for imbalances 2005 British Electricity Trading Transmission Arrangements (BETTA) includes Scotland 1990 Privatisation - 12 regional supply monopolies. Loads over 1 MW can choose their supplier Loads over 100 kw can choose their supplier 1999 Full retail competition 2014 Competition and Markets Authority (CMA) inquiry 2013 Electricity Market Reform

14 Initial privatised structure 1990 (England and Wales) Supply 12 regional companies Regulated Generation Transmission Distribution Customer NationalPower PowerGen Nuclear Electric National Grid 12 regional companies initially the same

15 Great Britain today: concentration in supply and generation integration of generation and supply

17 Elements of the Electricity Market Reform 1. Carbon price floor 2. Feed-in-tariffs though contracts for difference (CfDs) for all low carbon generation 3. A capacity mechanism 4. Emissions performance standard Sits on top of, does not replace, the underlying wholesale market! Sits on top of the EU Emissions Trading Scheme!

18 Carbon price floor the EU ETS context

21 The four stages of EMR how strike prices are determined Nuclear Stage 1 To 2017 Stage s Stage s Stage 4 late 2020s/beyond Current arrangements alongside new Contracts for Difference with prices set administratively Technologies mature (but at different rates) and some are able to enter competitive, technologyspecific auctions. Growing maturity of technologies and movement towards technology neutral auctions. Technologies are mature enough and the carbon price is high and sustainable enough to allow all generators to compete without intervention Mature renewables

22 The Levy Control Framework (LCF) capping costs to consumers An annual cap on EMR costs incurred by consumers Included: Renewables Obligation, Feed-in Tariffs and Contracts for Difference Excluded: capacity payments and energy demand measures 5.3bn cap in rising to 7.6bn by % headroom for contingencies Believed to be compatible with 30% renewables by 2020 LCF costs will rise with: a) lower wholesale market price; b) lower carbon price support; c) higher capacity mechanism price

23 Nuclear progress Hinkley Point EDF Energy Sites at Hinkley Point and Sizewell up to 6,400 MW AREVA EPR Passed Generic Design Assessment and site work started but no Final Investment Decision (FID) as yet Strike price agreed for Hinkley Point /MWh, 89.50/MWh if Sizewell developed 35 year inflation-linked contract Gained EU State Aid approval but Austria may appeal

24 Nuclear progress other consortia NuGen (Toshiba, GDF SUEZ) Moorside up to 3400 MW Westinghouse AP1000 Passed Generic Design Assessment Horizon Nuclear Power (Hitachi) Sites at Wylfa and Oldbury, 5400 MW Advanced Boiling Water Reactors Going through Generic Design Assessment

25 CfD administrative strike prices for renewables Biomass (with CHP) Biomass Conversion Hydro Landfill Gas Onshore Wind Offshore Wind Wave and tidal stream Large Solar PV year contracts.

26 CfD auctions allocating the funds available Three pots no fungibility between them. 1. Established technologies (onshore wind, PV, energy from waste with CHP, hydro (all >5 MW) + landfill gas and sewage gas 2. Less established technologies (offshore wind, wave, tidal stream etc) 3. Biomass conversion If pots are undersubscribed all get the administrative strike price If pots are oversubscribed, auction is triggered and all are paid the price of the last successful bid Current auction process under way

27 Anecdotal observations on CfD process Cost of capital for completed projects has fallen as planned projects can be attractive to long-term institutional investors (e.gf pension funds) Cost of capital for developers has gone up compared to the Renewables Obligation. The less established technologies pot could be used up by a single offshore wind project therefore risk of over-subscription and wasted preparatory work for developers

28 Capacity mechanism A market-wide mechanism for all generation nor supported by Renewables Obligation or CfDs Four years ahead - first auctions held December 2014 for Offers for 1 year, 3 years or 15 years of provision 65,000 MW of bids submitted, of which 49,300 MW accepted, of which 9,800 MW new/refurbished plant (174 MW demand side) Clearing price /kW/year lower than expected

29 Emissions Performance Standard 450 g/kwh for new or refurbished plant Compare to 370 g/kwh for new combined cycle gas turbine CCGT, 900 g/kwh for existing coal Effectively kills new coal without carbon capture and storage (CCS) Negotiations on two CCS projects still under way (one coal, one gas)

31 Market stabilisation reserve IEEJ: March All Rights Reserved. Future policy options Certainty beyond 2020 Carbon intensity target (g/kwh) for electricity in May be set in 2016 under the Energy Act Advocated by the Committee on Climate Change to provide certainty beyond Continuation of unabated coal Falling cost of compliance with the EU Industrial Emission Directive which would otherwise have taken coal off the system in the early 2020s. Could be operating at (low load factor) in 2030 Beefed up emissions performance standard to take existing coal off the system (application to existing plant, degression over time from 450 g/kwh) suggested by think tanks Reform of the EU ETS
